    TerryKing On The Water SOON

    Hi, I'm working on a project to prototype an Onboard Computer System (see http://www.boatdesign.net/forums/showpost.php?p=169204&postcount=81 and spin-off threads for details).

    Does anyone have data on Shock and Vibration levels found on various boats?

    I'm looking to understand requirements for Hard Drives, and other components.

    As I understand it, "Shock" is a hard single event of short duration. Like 100G's for 2 Milliseconds.

    As I understand it, "Vibration" is repetitive, from about 5 Hz to several hundred Hz, and typically less force, such as .5G for what we would think was "Heavy Vibration" if it was at 40 Hz or so from a 2500 RPM Prop.

    If you can help with this information, or suggest pointers to sources, or comment, please chime in.

    A chime, of course, would be something like .1G at 440Hz on a suspended piece of pipe :)
